Fiber‐Modified Open‐Graded Friction Courses: Unveiling Enhanced Workability and Durability in Pavements

Engineering Reports, Volume 8, Issue 1, January 2026.
Open‐Graded Friction Course (OGFC) mixtures for flexible pavements. ABSTRACT Open‐Graded Friction Course (OGFC) mixtures in flexible pavements are known for their efficient drainage characteristics, but concerns exist regarding their structural weaknesses and short lifespans. This study investigates methods to improve the mechanical performance of OGFC

Adaptation of environmental data to national and sectorial context: application for reinforcing steel sold on the French market [PDF]

, 2018
Purpose: Environmental data for steel products are generally proposed at a continental or a global scale. The question we are tackling here is: does the fact that steel as a global market necessarily reduces the need for national data?

Experimental Study on the Melting of Hydrogen‐Reduced Iron Ore Pellets in Electric Arc Furnace‐Type Slags

steel research international, Volume 97, Issue 1, Page 205-217, January 2026.
To realize fossil‐free steelmaking using hydrogen direct reduced iron (H‐DRI), melting operations must be fully understood and thereafter efficiently implemented. Lab‐scale experiments investigating melting progression of H‐DRI are combined with results from pilot‐scale electric‐arc furnace trials.

Hydrogen Direct Reduction: History and Pathways for Cost Reduction

cScience, Volume 1, Issue 1, December 2025.
ABSTRACT The steel industry, a critical pillar of global economic development, is highly energy‐intensive, accounting for approximately 7%–9% of global energy‐related CO2 emissions. The transition from traditional carbon‐intensive metallurgy to hydrogen‐based metallurgy represents a pivotal pathway for the green and sustainable development of the steel
